The Cansiglio Forest hides a myriad of sinkholes, pits, and swallow holes of all sizes, due to the karst morphology of the territory: the rain dissolves the limestone rock, slowly but inexorably forming these natural chasms and fissures on the ground. The Bus de la Lum is an abyss characterized by a single large vertical entrance shaft 180m high, which then develops into a very large and articulated underground complex. The depth of the shaft is best appreciated out of season, because in summer the lush vegetation tends to partially obscure the view. According to ancient beliefs, it is the dwelling of the Anguane or Anduane, fierce and evil witches, toothless, with long rusty nails instead of hair and sharp fangs, who kidnapped and ate children! They gathered at the bottom of the cave, lighting fires, whose glows rose to the surface, visible at night to the shepherds of the area: hence the name 'Buco della Luce' (Hole of Light). In reality, the legend has a grain of truth: on hot summer nights, will-o'-the-wisps could indeed be formed by the decomposing carcasses of livestock dead from illness, which it was customary to throw into the Buso. During World War II, the cavity was sadly used by partisans as a foiba, to dispose of the bodies of fascists and nazis, but also of civilians: over the years, several bodies and bones have been found during explorations. https://it.wikipedia.org/wiki/Bus_de_la_Lum

Unlike the classic Cansiglio loop, from Crosetta we descended towards Fregona for about 500 meters until reaching the 14% climb that leads to the Malghe trail. The route runs through Friuli Venezia Giulia, in the municipalities of Caneva and Polcenigo, through pastures. At km 7.41, we turn left to reach the Candaglia Forestry House and then resume the classic tour. We then reach Sant'Anna and Broz. From there, we climb back up to Campon to join the Taffarel.

The Gorgazzo springs have the characteristic of collecting rainwater which, infiltrating the karst structure of the Cansiglio plateau, emerges at the base of the mountain with an already considerable flow rate.

Panoramic view of Alpago. Peace. Looking down, you can see hidden behind the reliefs a tip of Lake Santa Croce, which always amazes with the clarity of its waters. Behind you, however, rise several peaks around 2000 m, among which is the Semenza bivouac.
